TRACK-SANDING APPARATUS.

Specification ofLetters Patent. Patent d Sept, 1, 1914.

Application filed April 17, 1912. Serial at. 691,458.

To all whom e't may concern Be it known that I, HAR Y Vrssnnmo, a citizen of the United States, and a resident of Chicago, in the State of Illinois, have in:

vented certain new and useful Improvements in Track-Sanding Apparatus, of which the following is a specification.

My present invention relates to' sand ejecting apparatus and more particularly to the track sanding apparatus commonly used at this day for applying sand adjacent thepoints of contact of the locomotive wheels with the rails and has special reference to the provision of a structure adapted for such application of sand upon the operation of the valve employed by the engineer in the operation of the air brakes.

The principal objects of my present invention are the provision of a form of sanding apparatus so arranged that upon movement of the air hrakecontrolling valve and more particularly movement thereof to emergency 7 position, sand will be autoniatically ejected from the apparatus; the

provision of means whereby the engineer may simultaneously operate the brakes and the sanding apparatus; the revision of combined means whereby the air brake and sanding apparatusmay be operated either simultaneously or independently; the provision of an improved form of controlling valve for the purpose referred to; the proyision of an improved form of material re straining means or sand trap having the required connections for such purpose and generally to improve sand strewing systems, together with such further objects as may hereinafter appear.

Track sanding apparatus as arranged for use at this day, as known to me, lacks pro-- vision of efiective means for simultaneously actuating the air brake and the track-sanding apparatus, since the, manipulation of the separate controlling valves is required. Of late no little trouble has been experienced in handling heavy trains, moreparticularly heavy fast passenger trains equipped with modern high-speed air brake equipment, in

the way of skid fiat wheels arising from emergency or other extra hard application of the air brakes without simultaneous actuation of the track sanding apparatus, and this especially duri damp Weather when the rail has a ten ency to become coming the greasy, ,I have therefore devised the present system, wherein the air for operating the san'denmaybe taken from a special connection on the engineers brake valve, so that uponjactuation of the brakes the sanding apparatus will be automatically actuated so as to efficiently apply the sand to the rail before the pressure of the brake on the wheels becomes suflicient to lock the wheels,

to prevent the engineer from cutting out the emergency sanding apparatus and thereby rendering it inoperative at the time when it is most required, I preferably dispose the connection between the engineers brake valve and the sand trap at a point where sand. will be admitted from the valve to the trap only when the valve is moved to emergency position, thus preventing frittering away of sand when the valve is on the'lap or running position or moved only to position v for ordinary service application of the brakes, and to, this end care is desirably used to avoidthe implacement of any stop, cock or cutout-cock of any kind between the brake valve and the trap.

In gaining the stated objects and overisadvantages referred to l have provided the constructions illustrated in the accompanying drawings wherein Figure 1 1s a diagrammatic elevational view of a railway locomotive having my improved track sanding apparatus applied thereto; Fig. 2 is an enlarged fragmentary plan view of part of the locomotive of Fig. 1; Figs. 3 and a are respectively an elevational view and a plan view of a form of duplex sand trap employed in the constructionillustrated .in Fig. 1; Figs. 5, 6 and C are respectively a plan, an elevational and an end view of a modified form of sand trap; and Fig. 8 is a plan view, partly in horizontal section, of a form of engineers brake valve employed by me in connection with the device of Fig. 1.

Referring first more particularly to Fig. 1, it will be noted that I have here illustrated somewhat conventionally a locomotive 10 having wheels 11 adapted to ride on rails 12. As a receptacle for containing a supply of sand the locomotive. 10. is provided with a .sand dome 13 with which communicate on both sides of the locomotive one or more traps, as indicated at 14, 14', 15,15,Q which serve to restrain the flow of sand from the receptacle 13 save when the apparatus is actuated. The traps referred to communicate with delivery pipes 16, 17, having noz- Zles 18, 19, adapted to deliver sand ad acent the points of contact of 'thewheels' 11, 11 with the rails 12, the pipe 16 being disposed for delivery of sand in front of'the wheels and the pipe 17 being disposed-ion delivery of sand to' therear thereof as desired when the engine is running backv rard. For ej'ectin sand contained 'in the traps 14, 15

throug the pipes 16,17 in alternation, 1-

provide in manually operated actuating means, the fluid conductor pipesin'dicated at 20, 21, connected to the traps14, 15 and to a three-way controlling valve 22 connected as by a pipe 23 to a source of fluid pres:

sure, such as the'main airreservoir 24' ofthe'air brake system, "which'i's supplied by an air compressor '(n'otshown).

on referringto Figlf2,- it will be observed that the traps 14, 14" -are'honiologous and that the traps 15, 15 are likewise homologous; furthermore that bythe employment of a suitable connection such as the pipes 20', 21 the manually ope'rated sander'just described is preferably so arrangedthat air is admitted simultaneously intothe traps 14, 14' or 15, 15. Againreverting to Fig. 1 it will likewise be apparent that I have here illustrated somewhat diagrammatically an air brake'system including the main air reservoir 24 above referred to, an engineers brake valve '25 connected to such reservoir 24 by a pipe 26, a brakecylinder 27 connected to the brake valve 25 by a pipe 28, a brake lever 29 fulcrumed at 30 and operable b fluid pressure admitted to said cylinder 2 through the pipe 28, the lever 29 being connected by abrake rod 31 to a brake beam fulcrumed at 32 to the framing 33, which beam carries. the brake head 34 provided with a shoe35 bearing on one of the wheels 11 in thecustomary manner. For admitting air to the traps 14,14'and 14',- 14', andthereby ejecting sand from such traps and applying it to the point of centact between the wheels 11 and the rail 12, simultaneously with the operation pecially upon emergen application thereof, and. independently of any operation of the valve 22, 1 provide on the brake valve 25 a special port 36 (see Fig. 8) connected by a pipe 37 and a branch thereoi 37 to portions of the traps 14, 14' shortly to be described,

'such port 36 being preferably so arranged as tobe-placed in communication with the reservoir 24 only when the handle of the brake valve 25 is moved to the emergency positi'onindicated in Fig. 8.

Gigi} air brakes,and es- Inasmuch as the traps 14, 14' are homologous I will now proceed to the description of the tra 14 only, in connection with Figs. 3 and-4, cm which it may be seen thatthe trap body 40' is adapted to. be attached at some convenient place adjacent the dome 13 by means of bolts passing through the holes 41, 42, and 43, is provided with suitable connections at 44, 44'. to receivethe pipes 37 and'20, has an opening at-45 communicating with the dome 13, and has at 46 a connection adapted to receive the discharge pipe 16. Arranged transversely through the body 10 between the connection 45 andthe closing plug 47 is a passage 48 communicating by passages 49, 49', 50, 50 with a transversely arranged passage 51 leading to the connection 46, the' passages between the connections 44 and 44' and the passage 48 'havin interposed therein nozzles'52 and 53,

and t e passages 49-50, 49'-50 having openings to the atmosphere (normally closed by caps 54, 54) whereby they may be cleaned. The construction just described in the present embodiment of my invention cares for'the sanding of the wheels when moving-forwardly whether the sand be dis charged manually through the operation of the sander valve 22 or automatically through the operation of the brake valve 25. For sanding the-wheels when the engineis moving rearwardly a similar arrangement of trap may be employed, it sufficient to form but ordinarily I find v referably integrally with the trap 14 just escribed, a similarly constructed trap 15 wherein I employ a -connectidn44 anozzle52, an opening 45,

passages 49*, 50; and a connection 46.

Referring 'now' more particularly to the deviceof Figs, 5, e and a, it be observed,

thatthe device here'illustrated is in all substantial respects similar to that of the device of Fi s. 3 and 4'save that in lieu of theduplicatlon of the portions 49 and 50,

as -indicated at 49 and 50', I introduce air from the pipe 37 into the trapil l" through the connection 44 and air from the pipe 20 through the connection 44, each of said connections communicating with the passage 45* and respectively having interposed in such-passage nozzles as indicated at 52 and 53". Inasmuch as in ordinary service application of the brakes, it is desirable to conserve the-air supply as far as may be, whereas in emergency application of the brakes the sanding apparatus is actuated by air vented in such application and no such need or conservation of pressure exists, and in the latter case. it is desirableto supply a larger quantity of sand to the rails, 1 preferably give the nozzle a larger orifice and hence greater carrying capacity than the nozzle 53, and likewise make theorifice of the nozzle 52 larger than thatof the nozzle 53*, thereby permitting the passage of a heavy blast of air through the pipe 37 when the valve 25 is moved to emergency posit-ion.

From thevforegoing d escr-iptionof my invention it will be observed that in theoperation thereof, either the front or rear sander may be operated manually by manipulation of the duplex cab valve 22, and that upon manipulation of the brake valve 25, in the present embodiment ofmy invention, on an emergency application of the brakes, the front sander will be operated automatically and simultaneously with the operation of the brakes Without concurrent manipulation of the valve 22, thus insuring at all times adequate and eiiicient suppl of sand adjacent the point of contact of th with the rails, atthe time such sand is most needed.
